Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668986, here are decompositions:

13 + 8668973 = 8668986
19 + 8668967 = 8668986
89 + 8668897 = 8668986
97 + 8668889 = 8668986
113 + 8668873 = 8668986
149 + 8668837 = 8668986
173 + 8668813 = 8668986
223 + 8668763 = 8668986

Showing the first eight; more decompositions exist.
